ABOUT THE CLIENT
SEMICONDUCTOR FACTORY IN MALAYSIA
Located in Bayan Lepas, Penang – widely regarded as one of Southeast Asia’s leading hubs for semiconductor and microelectronic manufacturing – a new and major microelectronic plant was established to support high-precision production.
Facilities of this scale rely on tightly controlled water systems to protect critical process equipment, making consistent water quality a fundamental requirement across the plant.
WHAT THE CLIENT NEEDED
RELIABLE MICROBIAL CONTROL
The plant’s process cooling water loop required effective protection against microbial growth and biofilm formation. In recirculating cooling systems, uncontrolled microbial activity can reduce heat transfer efficiency, foul heat exchangers, obstruct narrow cooling channels, and contribute to microbially influenced corrosion. For a microelectronic facility, these risks can ultimately affect equipment reliability and process stability.
The client needed a solution that would deliver consistent microbial control without introducing chemical residuals that could add to the maintenance burden or compromise the surrounding processes.
THE SOLUTION
CHEMICAL-FREE MICROBIAL CONTROL
In collaboration with Hydro Nusantara, two ULTRATRON MP1-2500SS UV systems were supplied and commissioned for the cooling water loop.
Based on the latest Medium-Pressure High Intensity (MPHI) ULTRATHERM lamp technology, the ULTRATRON series delivers high UV-C output density from a compact footprint, while the flanged connection and CFD-optimized lamp placement allow straightforward integration into existing infrastructure with minimal head loss.
By using UV light to inactivate microorganisms and disrupt their ability to replicate, the systems prevent biofilm formation and microbial regrowth without adding chemicals or leaving residuals.
The electropolished AISI 316L reactor improves internal reflection and efficiency, and the automated ULTRAWIPER quartz cleaning maintains stable performance with minimal maintenance.
With the two ULTRATRON systems in operation, the plant can maintain consistent water quality across its cooling loop, safeguarding critical processes for years to come.
